i find your comments in this thread are very childish and ignorant. We are ALL TOGETHER HERE trying to collaborate and figure out what the fuck the government is actually doing with the nano particles they are spraying in our atmosphere if you got nothing positive to add you should take your comments somewhere else.
For those misinformed/deceived....or hating,
Cloud Seeding......It is a multimillion dollar industry.
Maybe you are lucky and they dont do it where you live. I watch them control the weather often, its frustrating when they ruin a clear sunny day.
Some people choose to call cloud seeding "chem trails" for me they are the same thing. However, if you type in "chem trails" into wikipedia it says conspiracy theory, if you type in "cloud seeding" you get what I have copied and pasted below.
I encourage everyone to use the term "cloud seeding" because its scientifically accepted and therefore "credible". Chem trails usually gets you labeled as a crazy by the "average" (sheople) person who gets their information from mainstream television. The funniest is when people tell you that its a "contrail" which is frozen humidity from a planes wings. Contrails melt and have a short length, they look like airplane exhaust and I only see them at higher altitudes.
Cloud seeding
From Wikipedia, the free encyclopedia

Cloud seeding can be done by ground generators, plane, or rocket.
Cloud seeding, a form of intentional weather modification, is the attempt to change the amount or type of precipitation that falls from clouds, by dispersing substances into the air that serve as cloud condensation or ice nuclei, which alter the microphysical processes within the cloud. The usual intent is to increase precipitation (rain or snow), but hail and fog suppression are also widely practiced in airports.
This image explaining cloud seeding shows the chemical either silver iodine or dry ice being dumped onto the cloud which then becomes a rain shower. The process shown in the upper right is what is happening in the cloud and the process of condensation to the introduced chemicals.

The most common chemicals used for cloud seeding include silver iodide and dry ice (solid carbon dioxide). Liquid propane, which expands into a gas, has also been used. This can produce ice crystals at higher temperatures than silver iodide. The use of hygroscopic materials, such as salt, is becoming more popular[citation needed] after promising research [1].
Seeding of clouds requires that they contain supercooled liquid water—that is, liquid water colder than zero degrees Celsius. Introduction of a substance such as silver iodide, which has a crystalline structure similar to that of ice, will induce freezing nucleation.
Dry ice or propane expansion cools the air to such an extent that ice crystals can nucleate spontaneously from the vapor phase. Unlike seeding with silver iodide, this spontaneous nucleation does not require any existing droplets or particles because it produces extremely high vapor supersaturations near the seeding substance. However, the existing droplets are needed for the ice crystals to grow into large enough particles to precipitate out.
In mid-latitude clouds, the usual seeding strategy has been based on the fact that the equilibrium vapor pressure is lower over ice than over water. The formation of ice particles in supercooled clouds allows those particles to grow at the expense of liquid droplets. If sufficient growth takes place, the particles become heavy enough to fall as precipitation from clouds that otherwise would produce no precipitation. This process is known as "static" seeding.
Seeding of warm-season or tropical cumulonimbus (convective) clouds seeks to exploit the latent heat released by freezing. This strategy of "dynamic" seeding assumes that the additional latent heat adds buoyancy, strengthens updrafts, ensures more low-level convergence, and ultimately causes rapid growth of properly selected clouds.
Cloud seeding chemicals may be dispersed by aircraft (as in the second figure) or by dispersion devices located on the ground (generators, as in first figure, or canisters fired from anti-aircraft guns or rockets). For release by aircraft, silver iodide flares are ignited and dispersed as an aircraft flies through the inflow of a cloud. When released by devices on the ground, the fine particles are carried downwind and upwards by air currents after release.
An electronic mechanism was tested in 2010, when infrared laser pulses were directed to the air above Berlin by researchers from the University of Geneva.[2] The experimenters posited that the pulses would encourage atmospheric sulfur dioxide and nitrogen dioxide to form particles that would then act as seeds.[2]

Effectiveness
Referring to the 1903, 1915, 1919 and 1944 and 1947 weather modification experiments, the Australian Federation of Meteorology discounted "rain making." By the 1950s the CSIRO Division of Radiophysics switched to investigating the physics of clouds and had hoped by 1957 to better understand these processes. By the 1960s the dreams of weather making had faded only to be re-ignited post-corporatisation of the Snowy Mountains Scheme in order to achieve "above target" water. This would provide enhanced energy generation and profits to the public agencies who are the principal owners. Cloud seeding has been shown to be effective in altering cloud structure and size and in converting supercooled liquid water to ice particles. The amount of precipitation due to seeding is difficult to quantify.
A key challenge is in discerning how much precipitation would have occurred had clouds not been seeded. Overall, there is general expectation that winter cloud seeding over mountains will produce snow, expressed by professional organizations.[3][4][5][6] There is statistical evidence for seasonal precipitation increases of about 10% with winter seeding.[7]
The US government, through its National Center for Atmospheric Research, has analyzed seeded and unseeded clouds to understand the differences between them, and has conducted seeding research in other countries.[citation needed]
Clouds were seeded during the 2008 Summer Olympics in Beijing using rockets,[8] so that there would be no rain during the opening and closing ceremonies.[9] although others dispute their claims of success.[10]
A 2010 Israel University study revealed that the common practice of cloud seeding with materials such as silver iodide and frozen carbon dioxide may not be as effective as it had been hoped.[11] A 2011 study suggest that airplanes may produce ice particles by freezing cloud droplets that cool as they flow around the tips of propellers, over wings or over jet aircraft, and thereby unintentionally seed clouds. This could have potentially serious consequences for particular hail stone formation. [12]
Impact on environment and health
With an NFPA 704 rating of Blue 2, silver iodide can cause temporary incapacitation or possible residual injury to humans and mammals with intense or continued but not chronic exposure. However, there have been several detailed ecological studies that showed negligible environmental and health impacts.[13][14][15] The toxicity of silver and silver compounds (from silver iodide) was shown to be of low order in some studies. These findings likely result from the minute amounts of silver generated by cloud seeding, which are 100 times less than industry emissions into the atmosphere in many parts of the world, or individual exposure from tooth fillings.[16]
Accumulations in the soil, vegetation, and surface runoff have not been large enough to measure above natural background.[17] A 1995 environmental assessment in the Sierra Nevada of California[18] and a 2004 independent panel of experts (an overview only is presented in the executive summary of the research) in Australia confirmed these earlier findings.
Cloud seeding over Kosciuszko National Park - a Biosphere Reserve - is problematic in that several rapid changes of environmental legislation were made to enable the "trial." Environmentalists are concerned about the uptake of elemental silver in a highly sensitive environment affecting the pygmy possum amongst other species as well as recent high level algal blooms in once pristine glacial lakes. The ABC program Earthbeat on July 14, 2004 heard that not every cloud has a silver lining where concerns for the health of the pygmy possums was raised. Research 50 years ago and analysis by the former Snowy Mountains Authority led to the cessation of the cloud seeding program in the 1950s with non-definitive results. Formerly, cloud seeding was rejected in Australia on environmental grounds because of concerns about the protected species, the pygmy possum. Since silver iodide and not elemental silver is the cloud seeding material, the claims of negative environmental impact are disputed by peer-reviewed research as summarized by the international weather modification association.
History
Cessna 210 with cloud seeding equipment
Vincent Schaefer (1906–1993) discovered the principle of cloud seeding in July 1946 through a series of serendipitous events. Following ideas generated between himself and Nobel laureate Irving Langmuir while climbing Mt. Washington in New Hampshire, Schaefer, Langmuir's research associate, created a way of experimenting with supercooled clouds using a deep freeze unit of potential agents to stimulate ice crystal growth, i.e., salt, talcum powder, soils, dust and various chemical agents with minor effect. Then one hot and humid July 14, 1946, he wanted to try a few experiments at General Electric's Schenectady Research Lab.
He was dismayed to find that the deep freezer was not cold enough to produce a "cloud" using breath air. He decided to move the process along by adding a chunk of dry ice just to lower the temperature of his experimental chamber. To his astonishment, as soon as he breathed into the deep freezer, a bluish haze was noted, followed by an eye-popping display of millions of microscopic ice crystals, reflecting the strong light rays from the lamp illuminating a cross-section of the chamber. He instantly realized that he had discovered a way to change supercooled water into ice crystals. The experiment was easily replicated and he explored the temperature gradient to establish the −40˚C[19] limit for liquid water.
Within the month, Schaefer's colleague, the noted atmospheric scientist Dr. Bernard Vonnegut (brother of novelist Kurt Vonnegut) is credited with discovering another method for "seeding" supercooled cloud water. Vonnegut accomplished his discovery at the desk, looking up information in a basic chemistry text and then tinkering with silver and iodide chemicals to produce silver iodide. Together with Professor Henry Chessin, SUNY Albany, a crystallographer, he co-authored a publication in Science Magazine [20] and received a patent in 1975.[21] Both methods were adopted for use in cloud seeding during 1946 while working for the General Electric Corporation in the state of New York.
Schaefer's altered a cloud's heat budget, Vonnegut's altered formative crystal structure – an ingenious property related to a good match in lattice constant between the two types of crystal. (The crystallography of ice later played a role in Kurt Vonnegut's novel Cat's Cradle.) The first attempt to modify natural clouds in the field through "cloud seeding" began during a flight that began in upstate New York on 13 November 1946. Schaefer was able to cause snow to fall near Mount Greylock in western Massachusetts, after he dumped six pounds of dry ice into the target cloud from a plane after a 60-mile easterly chase from the Schenectady County Airport.[22]
Dry ice and silver iodide agents are effective in changing the physical chemistry of supercooled clouds, thus useful in augmentation of winter snowfall over mountains and under certain conditions, and lightning and hail suppression. While not a new technique, hygroscopic seeding for enhancement of rainfall in warm clouds is enjoying a revival, based on some positive indications from research in South Africa, Mexico, and elsewhere. The hygroscopic material most commonly used is salt. It is postulated that hygroscopic seeding causes the droplet size spectrum in clouds to become more maritime (bigger drops) and less continental, stimulating rainfall through coalescence. From March 1967 until July 1972, the U.S. military's Operation Popeye cloud-seeded silver iodide to extend the monsoon season over North Vietnam, specifically the Ho Chi Minh Trail. The operation resulted in the targeted areas seeing an extension of the monsoon period an average of 30 to 45 days.[23] The 54th Weather Reconnaissance Squadron carried out the operation to "make mud, not war".[24]
One private organization which offered, during the 1970s, to conduct weather modification (cloud seeding from the ground using silver iodide flares) was Irving P. Krick and Associates of Palm Springs, California. They were contracted by the Oklahoma State University in 1972 to conduct such a seeding project to increase warm cloud rainfall in the Lake Carl Blackwell watershed. That lake was, at that time (1972–73), the primary water supply for Stillwater, Oklahoma and was dangerously low. The project did not operate for a long enough time to show statistically any change from natural variations. However, at the same time, seeding operations have been ongoing in California since 1948.
An attempt by the United States military to modify hurricanes in the Atlantic basin using cloud seeding in the 1960s was called Project Stormfury. Only a few hurricanes were tested with cloud seeding because of the strict rules that were set by the scientists of the project. It was unclear whether the project was successful; hurricanes appeared to change in structure slightly, but only temporarily. The fear that cloud seeding could potentially change the course or power of hurricanes and negatively affect people in the storm's path stopped the project.
Two federal agencies have supported various weather modification research projects, which began in the early 1960s: The United States Bureau of Reclamation (Reclamation; Department of the Interior) and the National Oceanic and Atmospheric Administration (NOAA; Department of Commerce). Reclamation sponsored several cloud seeding research projects under the umbrella of Project Skywater from 1964 to 1988, and NOAA conducted the Atmospheric Modification Program from 1979 to 1993. The sponsored projects were carried out in several states and two countries (Thailand and Morocco), studying both winter and summer cloud seeding. More recently, Reclamation sponsored a small cooperative research program with six Western states called the Weather Damage Modification Program,[25] from 2002–2006.
Funding for research in the United States has declined in the last two decades. The Bureau of Reclamation sponsored a six-state research program from 2002–2006, however, called the "Weather Damage Modification Program".[26] A 2003 study[27] by the United States National Academy of Sciences urges a national research program to clear up remaining questions about weather modification's efficacy and practice.
In Australia, CSIRO conducted major trials between 1947 and the early 1960s:
1947 – 1952: CSIRO scientists dropped dry ice into the tops of cumulus clouds. The method worked reliably with clouds that were very cold, producing rain that would not have otherwise fallen.
1953 – 1956: CSIRO carried out similar trials South Australia, Queensland and other States. Experiments used both ground-based and airborne silver iodide generators.
Late 1950s and early 1960s: Cloud seeding in the Snowy Mountains, on the Cape York Peninsula in Queensland, in the New England district of New South Wales, and in the Warragamba catchment area west of Sydney.
Only the trial conducted in the Snowy Mountains produced statistically significant rainfall increases over the entire experiment.
An Austrian study[28] to use silver iodine seeding for hail prevention ran during 1981–2000, and the technique is still actively deployed there.[29]
Modern uses
Asia
The largest cloud seeding system in the world is that of the People's Republic of China, which believes that it increases the amount of rain over several increasingly arid regions, including its capital city, Beijing, by firing silver iodide rockets into the sky where rain is desired. There is even political strife caused by neighboring regions which accuse each other of "stealing rain" using cloud seeding. About 24 countries currently practice weather modification operationally[citation needed]. China used cloud seeding in Beijing just before the 2008 Olympic Games in order to clear the air of pollution, but there are disputes regarding the Chinese claims. In February 2009, China also blasted iodide sticks over Beijing to artificially induce snowfall after four months of drought, and blasted iodide sticks over other areas of northern China to increase snowfall. The snowfall in Beijing lasted for approximately three days and led to the closure of 12 main roads around Beijing.[30] At the end of October 2009 Beijing claimed it had its earliest snowfall since 1987 due to cloud seeding.[31]
In Southeast Asia, open burning produces haze that pollutes the regional environment. Cloud-seeding has been used to improve the air quality by encouraging rainfall. In India, cloud seeding operations were conducted during the years 2003 and 2004 through U.S. based Weather Modification Inc. in the state of Maharashtra.[32] In 2008, there are plans for 12 districts of state of Andhra Pradesh.[33]
In the United Arab Emirates, cloud seeding is being conducted by the weather authorities to create artificial rain.[34] The project, which began in July 2010 and cost $ 11 million, has been successful in creating rain storms in the Dubai and Abu Dhabi desert.[35]
North America
In the United States, cloud seeding is used to increase precipitation in areas experiencing drought, to reduce the size of hailstones that form in thunderstorms, and to reduce the amount of fog in and around airports. Cloud seeding is also occasionally used by major ski resorts to induce snowfall. Eleven western states and one Canadian province (Alberta) have ongoing weather modification operational programs [1]. In January 2006, an $8.8 million cloud seeding project began in Wyoming to examine the effects of cloud seeding on snowfall over Wyoming's Medicine Bow, Sierra Madre, and Wind River mountain ranges.[36]
A number of commercial companies offer weather modification services centered on cloud seeding. The U.S. signed an international treaty in 1978 banning the use of weather modification for hostile purposes.[37]
This Cessna 441 is used to conduct cloud-seeding flights on behalf of Hydro Tasmania
During the sixties, Irving P. Krick & Associates operated a successful cloud seeding operation in the area around Calgary, Alberta. This utilized both aircraft and ground-based generators that pumped silver iodide into the atmosphere in an attempt to reduce the threat of hail damage. Ralph Langeman, Lynn Garrison, and Stan McLeod, all ex-members of the RCAF's 403 Squadron, attending the University of Alberta, spent their summers flying hail suppression.
A number of surplus Harvard aircraft were fitted with racks under each wing containing 32 railroad fuzees that were impregnated with silver iodide. These could be ignited individually or all at once, depending upon the threat. In coordination with ground units, the aircraft would lay a plume of silver iodide in front of approaching cumulonimbus clouds with noticeable effect. Large, active CBs were reduced to nothing. Heavy hail storms were reduced in intensity. This effective program was funded by farmer contributions and government grants.[citation needed]
Europe
Cloud seeding began in France during the 1950s with the intent of reducing hail damage to crops. The ANELFA project consists of local agencies acting within a non-profit organization.[38] A similar project in Spain is managed by the Consorcio por la Lucha Antigranizo de Aragon.[38] The success of the French program was supported by insurance data; that of the Spanish program in studies conducted by the Spanish Agricultural Ministry.[38]
Soviet military pilots seeded clouds over the Belorussian SSR after the Chernobyl disaster to remove radioactive particles from clouds heading toward Moscow.[39] At the July 2006 G8 Summit, President Putin commented that air force jets had been deployed to seed incoming clouds so they rained over Finland. Rain drenched the summit anyway.[40] In Moscow, the Russian Airforce tried seeding clouds with bags of cement on June 17, 2008. One of the bags did not pulverize and went through the roof of a house.[41] In October 2009, the Mayor of Moscow promised a "winter without snow" for the city after revealing efforts by the Russian Air Force to seed the clouds upwind from Moscow throughout the winter.[42]
Australia
In Australia, the activities of CSIRO and Hydro Tasmania over central and western Tasmania between the 1960s and the present day appear to have been successful.[43] Seeding over the Hydro-Electricity Commission catchment area on the Central Plateau achieved rainfall increases as high as 30% in autumn. The Tasmanian experiments were so successful that the Commission has regularly undertaken seeding ever since in mountainous parts of the State.
In 2004, Snowy Hydro Limited began a trial of cloud seeding to assess the feasibility of increasing snow precipitation in the Snowy Mountains in Australia.[44] The test period, originally scheduled to end in 2009, was later extended to 2014.[44] The New South Wales (NSW) Natural Resources Commission, responsible for supervising the cloud seeding operations, believes that the trial may have difficulty establishing statistically whether cloud seeding operations are increasing snowfall. This project was discussed at a summit in Narrabri, NSW on 1 December 2006. The summit met with the intention of outlining a proposal for a 5 year trial, focussing on Northern NSW.
The various implications of such a widespread trial were discussed, drawing on the combined knowledge of several worldwide experts, including representatives from the Tasmanian Hydro Cloud Seeding Project however does not make reference to former cloud seeding experiments by the then Snowy Mountains Authority which rejected weather modification. The trial required changes to NSW environmental legislation in order to facilitate placement of the cloud seeding apparatus. The modern experiment is not supported for the Australian Alps.
In December 2006, the Queensland government of Australia announced A$7.6 million in funding for "warm cloud" seeding research to be conducted jointly by the Australian Bureau of Meteorology and the United States National Center for Atmospheric Research.[45] Outcomes of the study are hoped to ease continuing drought conditions in the states South East region.
Africa
In Mali and Niger, cloud seeding is also used on a national scale.[46][47]

Only a few hurricanes were tested with cloud seeding because of the strict rules that were set by the scientists of the project. It was unclear whether the project was successful; hurricanes appeared to change in structure slightly, but only temporarily. The fear that cloud seeding could potentially change the course or power of hurricanes and negatively affect people in the storm's path stopped the project.
Two federal agencies have supported various weather modification research projects, which began in the early 1960s: The United States Bureau of Reclamation (Reclamation; Department of the Interior) and the National Oceanic and Atmospheric Administration (NOAA; Department of Commerce). Reclamation sponsored several cloud seeding research projects under the umbrella of Project Skywater from 1964 to 1988, and NOAA conducted the Atmospheric Modification Program from 1979 to 1993. The sponsored projects were carried out in several states and two countries (Thailand and Morocco), studying both winter and summer cloud seeding. More recently, Reclamation sponsored a small cooperative research program with six Western states called the Weather Damage Modification Program,[25] from 2002–2006.
Funding for research in the United States has declined in the last two decades. The Bureau of Reclamation sponsored a six-state research program from 2002–2006, however, called the "Weather Damage Modification Program".[26] A 2003 study[27] by the United States National Academy of Sciences urges a national research program to clear up remaining questions about weather modification's efficacy and practice.
In Australia, CSIRO conducted major trials between 1947 and the early 1960s:
1947 – 1952: CSIRO scientists dropped dry ice into the tops of cumulus clouds. The method worked reliably with clouds that were very cold, producing rain that would not have otherwise fallen.
1953 – 1956: CSIRO carried out similar trials South Australia, Queensland and other States. Experiments used both ground-based and airborne silver iodide generators.
Late 1950s and early 1960s: Cloud seeding in the Snowy Mountains, on the Cape York Peninsula in Queensland, in the New England district of New South Wales, and in the Warragamba catchment area west of Sydney.
Only the trial conducted in the Snowy Mountains produced statistically significant rainfall increases over the entire experiment.
An Austrian study[28] to use silver iodine seeding for hail prevention ran during 1981–2000, and the technique is still actively deployed there.[29]
Modern uses
Asia
The largest cloud seeding system in the world is that of the People's Republic of China, which believes that it increases the amount of rain over several increasingly arid regions, including its capital city, Beijing, by firing silver iodide rockets into the sky where rain is desired. There is even political strife caused by neighboring regions which accuse each other of "stealing rain" using cloud seeding. About 24 countries currently practice weather modification operationally[citation needed]. China used cloud seeding in Beijing just before the 2008 Olympic Games in order to clear the air of pollution, but there are disputes regarding the Chinese claims. In February 2009, China also blasted iodide sticks over Beijing to artificially induce snowfall after four months of drought, and blasted iodide sticks over other areas of northern China to increase snowfall. The snowfall in Beijing lasted for approximately three days and led to the closure of 12 main roads around Beijing.[30] At the end of October 2009 Beijing claimed it had its earliest snowfall since 1987 due to cloud seeding.[31]
In Southeast Asia, open burning produces haze that pollutes the regional environment. Cloud-seeding has been used to improve the air quality by encouraging rainfall. In India, cloud seeding operations were conducted during the years 2003 and 2004 through U.S. based Weather Modification Inc. in the state of Maharashtra.[32] In 2008, there are plans for 12 districts of state of Andhra Pradesh.[33]
In the United Arab Emirates, cloud seeding is being conducted by the weather authorities to create artificial rain.[34] The project, which began in July 2010 and cost $ 11 million, has been successful in creating rain storms in the Dubai and Abu Dhabi desert.[35]
North America
In the United States, cloud seeding is used to increase precipitation in areas experiencing drought, to reduce the size of hailstones that form in thunderstorms, and to reduce the amount of fog in and around airports. Cloud seeding is also occasionally used by major ski resorts to induce snowfall. Eleven western states and one Canadian province (Alberta) have ongoing weather modification operational programs [1]. In January 2006, an $8.8 million cloud seeding project began in Wyoming to examine the effects of cloud seeding on snowfall over Wyoming's Medicine Bow, Sierra Madre, and Wind River mountain ranges.[36]
A number of commercial companies offer weather modification services centered on cloud seeding. The U.S. signed an international treaty in 1978 banning the use of weather modification for hostile purposes.[37]
This Cessna 441 is used to conduct cloud-seeding flights on behalf of Hydro Tasmania
During the sixties, Irving P. Krick & Associates operated a successful cloud seeding operation in the area around Calgary, Alberta. This utilized both aircraft and ground-based generators that pumped silver iodide into the atmosphere in an attempt to reduce the threat of hail damage. Ralph Langeman, Lynn Garrison, and Stan McLeod, all ex-members of the RCAF's 403 Squadron, attending the University of Alberta, spent their summers flying hail suppression.
A number of surplus Harvard aircraft were fitted with racks under each wing containing 32 railroad fuzees that were impregnated with silver iodide. These could be ignited individually or all at once, depending upon the threat. In coordination with ground units, the aircraft would lay a plume of silver iodide in front of approaching cumulonimbus clouds with noticeable effect. Large, active CBs were reduced to nothing. Heavy hail storms were reduced in intensity. This effective program was funded by farmer contributions and government grants.[citation needed]
Europe
Cloud seeding began in France during the 1950s with the intent of reducing hail damage to crops. The ANELFA project consists of local agencies acting within a non-profit organization.[38] A similar project in Spain is managed by the Consorcio por la Lucha Antigranizo de Aragon.[38] The success of the French program was supported by insurance data; that of the Spanish program in studies conducted by the Spanish Agricultural Ministry.[38]
Soviet military pilots seeded clouds over the Belorussian SSR after the Chernobyl disaster to remove radioactive particles from clouds heading toward Moscow.[39] At the July 2006 G8 Summit, President Putin commented that air force jets had been deployed to seed incoming clouds so they rained over Finland. Rain drenched the summit anyway.[40] In Moscow, the Russian Airforce tried seeding clouds with bags of cement on June 17, 2008. One of the bags did not pulverize and went through the roof of a house.[41] In October 2009, the Mayor of Moscow promised a "winter without snow" for the city after revealing efforts by the Russian Air Force to seed the clouds upwind from Moscow throughout the winter.[42]
Australia
In Australia, the activities of CSIRO and Hydro Tasmania over central and western Tasmania between the 1960s and the present day appear to have been successful.[43] Seeding over the Hydro-Electricity Commission catchment area on the Central Plateau achieved rainfall increases as high as 30% in autumn. The Tasmanian experiments were so successful that the Commission has regularly undertaken seeding ever since in mountainous parts of the State.
In 2004, Snowy Hydro Limited began a trial of cloud seeding to assess the feasibility of increasing snow precipitation in the Snowy Mountains in Australia.[44] The test period, originally scheduled to end in 2009, was later extended to 2014.[44] The New South Wales (NSW) Natural Resources Commission, responsible for supervising the cloud seeding operations, believes that the trial may have difficulty establishing statistically whether cloud seeding operations are increasing snowfall. This project was discussed at a summit in Narrabri, NSW on 1 December 2006. The summit met with the intention of outlining a proposal for a 5 year trial, focussing on Northern NSW.
The various implications of such a widespread trial were discussed, drawing on the combined knowledge of several worldwide experts, including representatives from the Tasmanian Hydro Cloud Seeding Project however does not make reference to former cloud seeding experiments by the then Snowy Mountains Authority which rejected weather modification. The trial required changes to NSW environmental legislation in order to facilitate placement of the cloud seeding apparatus. The modern experiment is not supported for the Australian Alps.
In December 2006, the Queensland government of Australia announced A$7.6 million in funding for "warm cloud" seeding research to be conducted jointly by the Australian Bureau of Meteorology and the United States National Center for Atmospheric Research.[45] Outcomes of the study are hoped to ease continuing drought conditions in the states South East region.
Africa
In Mali and Niger, cloud seeding is also used on a national scale.[46][47]
wow, just wow.
and here i am stuck living in the real world. damn. i feel like i'm really missing out.
and here i am stuck living in the real world. damn. i feel like i'm really missing out.
you claim cloud seeding & chem-trails as being the same thing.
one is supposedly done in clouds
and
the other are trails across a clear blue sky.
conspiracy theorists have an out or answer for everything, so what's the truth here.......
i for one think the truth here is we dont know what they are doing because they dont tell us.. i would imagine for the same reasons they dont tell us about most of what the get up to behind closed doors..
I think what people refer to as "chem trails" are in fact "cloud seeds".
Those checkered lines they leave in the sky turn into clouds.
This has to do with VPD which is something I'm sure you are familiar with because it applies to growrooms.
Some people call the lines "trails" and some people call silver iodide that the "trail" is made of "chemicals".
Ski resorts in Colorado use cloud seeding to increase snow fall.
Some people make correlations between aluminum that is sometimes used in cloud seeding and fluoride in drinking water and toothpaste.
This is one instance where the "cloud seed" becomes the "Chem trail"
What is the long term and short term effect of releasing this shit into the air we breath?
Maybe if it was male pollen being released into our atmosphere more smart growers would be concerned with this dumb stuff.
According to Wikipedia..
China used cloud seeding before the Olympics.
8.8 million spent in Wyoming in 2006. To increase snowfall.
If you have no problems and no concerns with people "modifying" the weather without your consent, please move along and let us conspire in peace (paranoia)
The "scientific" fact is, they are modifying weather.
My concern is, I don't believe it's good to release "minuscule" amounts of toxins to make it rain....

I understand where you're coming from, we'll never know the whole truth but if we did, if they told us the 100% unadulterated truth, if we knew that all of their efforts to alter the weather failed would we believe them???
No!
the conspiracy theory stuff will continue into eternity, there will ALWAYS be someone gullible enough to believe he's being lied to because someone says it's so, I for one am tired of it.......
Their efforts to alter weather haven't failed and that's why it's a multimillion dollar industry..
gimme a break, I noticed you've picked me exclusively to level your petty insults on, that's okay 'cuz I've got thick skin.
the positive influence I'm providing here is common sense. there's NO DOUBT that over time the govt has tried to alter the weather, to accuse them of creating a storm killing well over 100 people is ridiculous, they're not that fucking good at creating anything and you know it.
chem-trails? as long as jets cross the skies there will be a vapor trail of some kind and too many 'enlightened' citizens pointing at it and whispering in conspiratorial tones.
when you figure out what the govt's really up to be sure and let the rest of us know.......

sorry to burst bubbles, but cloud seeding is far from being an exact science; the success rate is quite low and anyone claiming cloud seeding is manipulating the weather at will is just a simpleton ignoramuse, end of story.
either learn the facts or keep on being a misinformed fear monger
either learn the facts or keep on being a misinformed fear monger
I hope you meant multibillion, nobody's in jack shit for less than billions these days. to keep a conspiracy THIS BIG quiet you'd have to ply the frigging masses with millions of $$$, who the hell would risk their military pension, govt pension, their McMansions, their children's welfare for a cheeseburger handout?
okay, millions or billions I'm still not buying it, we are slaves to the ways of mother natures weather, always have and always will be.......
anyone believe in Alex Jones?
this is really good stuff.

IMO based on my own research.
More likely that most "airplanes" out there spewing out "chemtrails" are really "UFO" using hologram technology to camouflage itself. Why are they doing that? So many theories... the hole runs very deep.

Ben Livingston: The Father of Weaponized Weather
http://www.youtube.com/watch?v=MKl9rqw1Ykw
Veteran weather modification expert Ben Livingston is a former Navy Physicist who briefed President Lyndon B. Johnson on the effectiveness of weather control back in the 1960's during the Vietnam era, when he was involved in cloud seeding programs that worked to slow down the advance of Vietnamese and Korean troops. Livingston asserts that asserts that hurricane control was a national priority of the government more than 40 years ago and that the technology was fully operational to control the weather at the time.
In this exclusive interview for Prison Planet.tv subscribers, Livingston explains how for decades the US government has had the power to both lessen and increase the severity of adverse weather for their own purposes.
Dr. Livingston was assigned in 1966 from the Naval weapons research Laboratory to a marine fighter squadron in Vietnam. Instead of guns, the aircraft under Livingston's control were fitted with cloud seeding equipment. "My mission was to find clouds and seed them for maximum precipitation value" he stated.
Dr. Livingston presents evidence from the Stanford research Institute, who were brought into Project Storm Fury (a weather control program) in the late sixties as a third party, which stated conclusively that knowledge of how to stop hurricanes had been uncovered and that they would be directly liable should a hurricane hit and cause extensive damage and loss of life. Four decades later and Livingston exposes how the devastation caused by Hurricane Katrina could have been greatly minimized but was allowed to fully impact Gulf states for political reasons.
Having personally flown on 265 missions into the eyes of hurricanes, Livingston remarks that he was "disgusted" by the failure to lessen the impact of Katrina. Livingston's revelations that weather control has been a decades long program in which the US government has been deeply involved are particularly alarming given the abundant modern-day evidence of how chemtrails are being used to warp our environment in a secret geoengineering plot that threatens a myriad of unknown human health and ecological consequences.

Stoner4Life, I am curious what your not buying.
I believe that diverse opinions are healthy, other perspectives and points of view are key for evolution of thoughts, ideas, beliefs etc. I'm just trying to understand what your stance is.
Cloud seeding is real, and it actually works.
HERE is a short article about the success of bringing rain to a dry region in West Africa.
http://www.source.irc.nl/page/10355
Someone else is already buying it and in some cases with tax money.
The effects on us that chemicals used for cloud seeding is what concerns me and many of the other people in this discussion.
"With an NFPA 704 rating of Blue 2, silver iodide can cause temporary incapacitation or possible residual injury to humans and mammals with intense or continued but not chronic exposure."
But what is nfpa anyway...
The National Fire Protection Agency...
Ok so its not very explosive..
What does the EPA say about it.
Well after reading the MSDS that Deep Water Chemicals has....
I found this....
Clean Water Act- This material is listed as a Hazardous Substance, Priority
Pollutant and as a Toxic Pollutant.
So silver Iodide is a toxic pollutant.
First Aid Measures
Eyes: Flush with copious amounts of water for 15 minutes, occasionally lifting the upper and
lower lids. SEEK MEDICAL ATTENTION if irritation persists.
Skin: Wash skin with copious amounts of water and soap for 15 minutes while removing any
contaminated clothing and shoes. SEEK MEDICAL ATTENTION if irritation persists.
Ingestion: Induce vomiting immediately as directed by medical personnel. Never give
anything by mouth to an unconscious person. SEEK MEDICAL ATTENTION IMMEDIATELY.
Inhalation: Remove from exposure to fresh air immediately. If not breathing, give artificial
respiration. If breathing is difficult, give oxygen. SEEK MEDICAL ATTENTION IMMEDIATELY.
If it doesn't control the weather and its toxic.... why is it being released in the air we breathe. I dont want my kids or grandkids having health issues because of "cloud seeding" that MY generation thought was dumb stuff.
Maybe it wont effect us at all, but it concerns me when something like altering the weather doesn't appear to be regulated.
Not that I have done extensive research, but the people who verify that it isn't bad for the environment seem very similar to the FDA saying cannabis has no medical value. Just MHO
Its listed in the Clean Water Act as toxic.
So who says its not toxic.... The "Weather Modification Association" ......well that doesn't sound biased at all.
If I had my choice, I would probably "vote" no on putting silver Iodide into my clear skies..
Unfortunately I dont have that choice or vote at this moment, but perhaps in the future if enough of us get together and discuss our ideas, that will be "modified"
Ben Livingston......wow.
I've not denied the us govt has been seeding clouds for years, they've been doing it for decades. I am however denying 1000% that they had ANYTHING to do with engineering hurricane Sandy which was the op here.
if it will make you all feel warm n' fuzzy inside I'll tell ya your govt is lying to you, I'm done with this shit.......
Yeah its kind of hard to argue with a person who has flown into 265 hurricanes
